There are known methods in the medical technology for performing the cryogenic therapy by exposing some parts of the human body or the whole body to the agents reducing their temperature. It is carried out by using the evaporation of condensed gases or compressed gases. The known devices for carrying out the cryogenic treatment have the therapeutical chamber. The patient, the cryogenic gas loading system, the control system and the protecting system etc are inside the chamber.

There is known from the German Patent Specification no. 3213919 the device for preparating the cryogenic air which is provided to the medical cryogenic chamber. The device has the air compressor, the dryer for removing the steam from the compressed air, the heat exchanger and the condensed gas container. The device is provided with the measuring elements, the control elements and the protective elements. The parts of the device which contain the cryogenic agents are provided with the thermalinsulation. The device requires a long starting time and a stand-by system.

From the Polish Patent Specification no 157168 the device is known for carrying out the cryogenic treatment which has the chamber for patients and the chamber cryogenic air loading unit. The chamber has the loading air circulation system having the air compressor, the dryer and the air cooling circulation system. The cooling air circulation system has the liquid gas vessel and the heat exchangers, wherein it has three heat gas exchangers ie; the preliminary heat exchanger, the main heat exchanger and the final heat exchanger as well as the spraying element. The preliminary heat exchanger and the spraying element are situated inside the chamber for the patients. The device has the favourable operating characteristics displayed in the short starting time and closing time.

The aim of the present invention is to provide the method and the cryogenic device which are directed to carrying out the safe treatment on the whole body of one or several patients.

The method according to the invention should provide correct and effective treatment, and the device according to the invention should provide the correct supply to the therapeutic chamber wherein the loaded gas has optimal parameters because of the treatment reasons. It should make possible the economical process by taking advantage of the deposition of low temperature gas phenomenon.

The method for carrying out the cryogenic therapy, particularly on the whole body of the patient characterised by that the patient or the patients are introduced along the transport route through the upper part of the chamber, and then through the interior of the chamber wherein the chamber has the thermally insulated walls, and containing the space with the deposited low temperature cooling agent to the cryogenic treatment cabin having very low temperature from −60 C. to −160 C., where the exposure time ranges from 0,5 to 5 minutes, after words the patient or the patients are led out of the treatment cabin through the interior of the chamber having the space with the deposited low temperature cooling agent then along the transport route outside the chamber to the room temperature area.

The device for carrying out the cryogenic therapy, particularly on the whole body of the patient characterised by that it has a chamber with an open upper part wherein the chamber has thermally insulated walls and containing the space with the deposited low teperature cooling agent and inside the chamber there is the treatment cryogenic cabin separated which is cooled in its whole volume by the cooling agent in the form of the liquid air spried by the nozzles .

The modyfication of the device for carrying out the cryogenic therapy, particularly on the whole body of the patient characterised by that it has a chamber with an open upper part wherein the chamber has thermally insulated walls and containing the space with the deposited low teperature cooling agent and inside the chamber there is the treatment cryogenic cabin separated which is cooled in its whole volume by the cooling agent in the form of the liquid carbon dioxide or liquid nitrogen spried by the nozzles wherein the chamber has in the upper part the air intake device which provides the breathing air for the patient or the patients.

The device for carrying out the cryogenic therapy, and its modyfication according to the invention characterised that the chamber has in the upper part the movable cover which is preferably transparent wherein the chamber has the chamber lighting elements and the cryogenic therapeutical cabin wherein the cabin has the emergency door situated in the side surface of the chamber which enables the access to the disabled people on wheelchairs and the chamber has the measuring and control temperature and oxygen concentration system which protects the patient or the patients.

It is advantageous to perform the cryogenic therapy, particularly on the whole body of the patient according to the present invention because it allows for the correct treatment thanks to the preliminary cooling of the patient's body, which is conducted in the space with the deposited low teperature cooling agent in the chamber, and the next step which is introducing the patient into the treatment cabin. After using the cabin the patient is gradually led out to the normal temperature area through the space with the deposited low teperature cooling agent in the chamber.

It is advantageous to use the device for carrying out the cryogenic therapy, particularly on the whole body of the patient according to the present invention and its modyfication becouse it enables high efficiency by reducing the loss of heat while the patient enters and leaves the chamber through the upper part of the chamber and the space with the deposited low teperature cooling agent to the treatment chamber. The reduction of the loss of the heat was obtained by using the movable transparent cover situated above the upper part of the chamber shielding it partially or completely while the patient or the patients are staying inside the cabin and when the cabin is empty. The lighting elements are situated in the internal surfaces of the chamber and allow for the comfortable conditions for the patient and the emergency door situated in the side surface of the chamber enable the direct exit of the patient from the cabin.
